DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-10 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Reference Figure 1 and Figure 2 A quick-release car seat fixing device includes a base fixing plate 2 and a sliding track 1. The base fixing plate 2 is detachably mounted on the sliding track 1 and is slidably connected to the sliding track 1. A sliding groove 11 is formed in the sliding track 1 along its length. Limiting plates 12 are fixedly mounted horizontally on both sides of the sliding groove 11. A plurality of mounting holes 13 are formed on the surface of the limiting plate 12 along its length. The spacing between adjacent mounting holes 13 is the same.

[0033] Reference Figure 3-Figure 6The base fixing plate 2 is provided with a limit hole 21, two locking holes 22, and several mounting screw holes 23 along its length. The limit hole 21 is located at the center of the base fixing plate 2, and the two locking holes 22 are located on either side of the limit hole 21. The spacing between the limit hole 21 and the locking hole 22 is greater than the spacing between two adjacent mounting holes 13. The mounting screw holes 23 are divided into two groups, one on the side of the locking hole 22 away from the limit hole 21 and symmetrically about the limit hole 21. Accordingly, a limit member 26, two locking members 27, and several sliding members 25 are provided on the base fixing plate 2. The sliding members 25 include a sliding rod 251 and a sliding head 252. To secure the sliding members 25 to the base fixing plate 2, a mounting screw 253 is provided at the end of the sliding rod 251 away from the sliding head 252. The mounting screw 253 on each sliding member 25 is threadedly engaged with the mounting screw hole 23 of the base fixing plate 2. A plurality of seat fixing holes 24 are formed on the surface of the base. Each seat fixing hole 24 is located between two adjacent mounting screw holes 23. The seat fixing holes 24 are provided for fixing and installing the seat.

[0034] Reference Figure 7 and Figure 8 The locking member 27 includes a locking screw 271, a locking sleeve 272, and a locking knob 273. The locking screw 271 is passed through the locking hole 22 and then threadedly connected to the locking sleeve 272. To facilitate the rotation of the locking screw 271, an anti-rotation surface 2711 is formed on one end of the locking screw 271, and an anti-rotation hole 2733 is formed on the surface of the locking knob 273 to match the anti-rotation surface 2711. The end of the locking screw 271 provided with the anti-rotation surface 2711 is inserted into the anti-rotation hole 2733, so that the locking screw 271 can be rotated by turning the locking knob 273. To prevent the locking knob 273 from falling off from the locking sleeve 272, an annular groove 2721 is formed on the side surface of the locking sleeve 272, and a fixing screw hole 2731 is formed on the side surface of the locking knob 273. After the locking knob 273 is sleeved around the locking sleeve 272, a fixing bolt 2732 is screwed into the fixing screw hole 2731 of the locking knob 273, and the end of the fixing bolt 2732 is locked into the annular groove 2721 of the locking sleeve 272. This not only ensures a secure installation between the locking knob 273 and the locking sleeve 272, but also provides the advantage of easy disassembly.

[0035] Reference Figure 9 and Figure 10The limiting member 26 includes a limiting knob 261, a fixing pin 262, a tension spring 263, and a guide sleeve 264. The guide sleeve 264 is fixedly arranged above the limiting hole 21 of the base fixing plate 2. To this end, a first screw thread 2641 is formed on the bottom end of the outer surface of the guide sleeve 264, and a second screw thread 211 is formed on the inner wall surface of the limiting hole 21, thereby threading the guide sleeve 264 into the limiting hole 21. The fixing pin 262 is vertically fixed at the bottom end of the anti-slip knob and inserted into the guide sleeve 264. The tension spring 263 is sleeved around the outer periphery of the fixing pin 262, and the two ends of the tension spring 263 are respectively fixed to the base fixing plate 2 and the limiting knob 261. The fixing pin 262 is inserted into the limiting hole 21 under the action of the tension spring 263.

[0036] To facilitate position adjustment of the base fixing plate 2 on the sliding track 1, a guide groove 2642 is formed on the outer surface of the guide sleeve 264. The bottom surface of the guide groove 2642 is curved, and a first groove 2643 and a second groove 2644 are respectively formed at both ends of the bottom surface of the guide groove 2642. The horizontal height of the first groove 2643 is lower than that of the second groove 2644. Correspondingly, a guide post 2611 is vertically formed on the inner side wall of the limit knob 261. The limit knob 261 is installed and sleeved on the outer periphery of the guide sleeve 264, so that the guide post 2611 is embedded in the guide groove 2642 and can slide along the bottom surface of the guide groove 2642, thereby adjusting the length of the fixing pin 262 extending from the limit hole 21. During adjustment, the limit knob 261 is rotated to make the guide column 2611 slide along the bottom surface of the guide groove 2642, and anti-slip grooves 2612 are formed on the outer surfaces of the limit knob 261 and the locking knob 273, thereby increasing the friction between the hand and the limit knob 261, and the hand and the locking knob 273 during the rotation process, thereby avoiding slipping during the rotation process.

[0037] When the end of the guide column 2611 is embedded in the first groove 2643, the top of the guide sleeve 264 abuts against the top wall of the limit knob 261, and the fixing pin 262 is extended out of the limit hole 21 to the maximum extent and can be embedded in the mounting hole 13 of the sliding track 1. When the limit knob 261 is rotated, when the guide column 2611 slides in the guide groove 2642, and when the end of the guide column 2611 is embedded in the second groove 2644, the top of the guide sleeve 264 maintains a distance from the top wall of the limit knob 261, and the end of the fixing pin 262 is passed through the limiting hole 21 and is flush with the bottom end surface of the base fixing plate 2, thereby facilitating the pushing of the base fixing plate 2 on the sliding track 1 for position adjustment, so as to prevent the fixing pin 262 from being automatically stuck in the other mounting holes 13 of the sliding track 1 under the action of the tension spring 263 during the position adjustment of the base fixing plate 2, thereby interrupting the position adjustment of the base fixing plate 2, thereby realizing quick release and quick adjustment between the base fixing plate 2 and the sliding track 1.

[0038] The specific implementation principle of the embodiment of the present application is as follows: when the base fixing plate 2 and the sliding track 1 need to be installed, the sliding head 252 and the locking screw 271 on the base fixing plate 2 are respectively inserted into the mounting hole 13 of the sliding track 1. Since the spacing between the limiting hole 21 and the locking hole 22 is greater than the spacing between two adjacent mounting holes 13, when the sliding head 252 and the locking screw 271 are respectively inserted into the mounting hole 13 of the sliding track 1, the end of the fixing pin 262 of the limiting member 26 abuts against the surface of the limiting plate 12 of the sliding track 1; the limiting knob 261 is rotated to cause the guide post 2611 on its inner side wall to slide along the bottom surface of the guide groove 2642 until the end of the guide post 2611 is inserted into the first groove 2643.

[0039] The base fixing plate 2 is pushed to slide on the sliding track 1. During the sliding process, the fixing pin 262 is engaged with the mounting hole 13 of the sliding track 1 by the action of the tension spring 263. At this time, the sliding head 252 of the sliding member 25 is located at the bottom end of the two limit plates 12, and the sliding rod 251 of the sliding member 25 is located between the two limit plates 12. The head of the locking screw 271 of the locking member 27 is located at the bottom end of the two limit plates 12, and the rod of the locking screw 271 of the locking member 27 is located between the two limit plates 12. Then, the locking knob 273 is turned to drive the locking screw 271 to rotate until the head of the locking screw 271 contacts the bottom surface of the limit plate 12, thereby locking the base fixing plate 2 to the sliding track 1 via the locking member 27.

[0040] When the position between the base fixing plate 2 and the sliding track 1 needs to be adjusted, the limit knob 261 is rotated to cause the guide post 2611 to slide along the bottom surface of the guide groove 2642 into the second groove 2644, thereby driving the fixing pin 262 to be pulled out of the mounting hole 13 of the sliding track 1. The locking knob 273 is then rotated in the opposite direction so that the head of the locking screw 271 no longer abuts against the bottom surface of the limit plate 12, thereby driving the base fixing plate 2 to slide on the sliding track 1, thereby adjusting the position of the base fixing plate 2. The multiple seat fixing holes 24 provided on the base fixing plate 2 are used for fixing and installing the seat, thereby enabling the automobile seat fixing device to achieve quick release and quick adjustment of the seat.

[0041] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all protected by the present invention.
